摘要：
An electric railway smart microgrid system (ERSMS) with integration of multiple energy systems is proposed to reduce the energy consumption of the railway system and improve the power quality. Compared with the traditional ERSMS, the proposed ERSMS introduces the railway station distribution power system and the function of power-to-gas to the smart microgrid system, which can significantly alleviate the burden of the energy-storage system and improve the utilization rate of energy inside the railway system. First, the structure of the ERSMS is introduced. Then, the working models of the system are analyzed. Subsequently, an energy management strategy and converter control strategy are designed to improve the energy regulation and power quality. Finally, the effectiveness of the proposed smart microgrid system is verified by case studies.
